YAD - Tips

[stemsee]

Code: Select all

export z

[achim]

@ Stemsee,

where exactly should I enter the code?

[achim]

with "export z" I already tested yesterday, unfortunately did not work, strange

[stemsee]

Hi achim, probably there are different ways, but what I would do is pipe to a yad --text-info dialog, like this:

Code: Select all

cd $CAMERA/
(
z=0
for f in *.jpg; do name=`echo "${f%.*}"`; echo "Kopiervorgang des Bildes "$f" läuft..."
   rsync -t $CAMERA/"$f" $ZIEL/$DATE/;
   z=$(($z+1)); export z;

echo "Der Kopiervorgang des Bildes"

echo "$f"

echo "wird als laufende Nr. $z durchgeführt..."
echo "$z Bilder kopiert"
done
) | yad --text="Kopiervorgang des Bildes" --width=600 --height 200 --fixed --window-icon="$HOME/.icons/Movies-icon24.png" --text-info --wrap --tail \
--title="Verlaufskontrolle" --text-align=center --no-buttons

because you want the last value assigned to z, not the first. So z gets updated on each iteration of the loop. You could write it to a file in /tmp ((NOTE BENE not '[' but '(( ))'

Code: Select all

z=$((z + 1)); echo "z=$z" >/tmp/z

[achim]

... You could write it to a file in /tmp ...

I would like to choose this option. Just how do I call the variable later - z=$(/tmp/z) ?

[stemsee]

Code: Select all

. /tmp/z

this imports the variable and its value into the script/command that calls it.

please note that the file in /tmp could be called anything .... /tmp/MYNAME

Code: Select all

. /tmp/MYNAME
echo "$z"
12

you can check the contents with

Code: Select all

cat /tmp/MYNAME
z=12

non pipe version. type on commandline and hit enter to send.

How to make it send as it is being typed without newlines until return is hit??

Code: Select all

while true; do read ound; echo "$ound"; done | yad --text-info --listen --width=200 --height=200

Code: Select all

buffer="";  while true; do IFS='' read -N 1 ound;  [[ "${buffer}" == *$'\n'* ]] && buffer=""; buffer="${buffer}${ound}"; echo -e "\f"; echo "${buffer}"; done | yad --text-info --listen --width=200 --height=200

even better with --tail option

Code: Select all

buffer="";  while true; do IFS='' read -N 1 ound; buffer="${buffer}${ound}"; echo -e "\f"; echo "${buffer}"; done | yad --text-info --listen --width=200 --height=200 --tail

Hello stemsee,

now the script works! thanks again

I see the trick! refresh after each character while remembering all previous typing.

backspace is not possible!?

[MochiMoppel]

backspace is not possible!?

Try this:

Code: Select all

while true ;do
	IFS='' read -rsN 1 ound
	if [[ $ound == $'\x7f' ]] ;then
		buffer=${buffer%?}
		echo -ne "\b" >&2
	else
		buffer=$buffer$ound
		echo -n "$ound" >&2
	fi
	echo -e "\f"
	echo "$buffer"
done | yad --text-info --width=200 --height=200 --tail

Added: read options -r (to allow direct entry of backslash character) and -s (to prevent ugly terminal output when entering backspace)
Removed: yad option --listen

@misko_2083: Clever approach

[stemsee]

@MochiMoppel
Amazingly good .... even does away with refresh flickers! .It could have been you who hacked Neo's cli??

[step]

@MochiMoppel, WOW! Thanks.

[misko_2083]

@misko_2083: Clever approach

It depends.
A few sentences and it's fine.
More new lines/chars - more refresh glitch.
Milions of characters in a variable and you run out of memory.
Though, it's very unlikely that stemsee will use this method to write a book.

Bit off topic:
Wanted to have something siimilar to the MATE desktop shutdown timer, only for the Xfce desktop.
It would run xfce4-session-logout -h after the timeout or a shutdown button click.
Yad does not let me change the text label so... resorted to c and gtk3.

Save next as timer.c

Code: Select all

#include <stdio.h>
#include <string.h>
#include <gtk/gtk.h>

/* Shutdown timer */

static      gboolean continue_timer = FALSE;
static      gboolean start_timer = TRUE;
static      int sec_expired = 30;

/* Shutdown command here */
static      gchar      *command[] = { "xfce4-session-logout -h",NULL };
GError     *error = NULL;

static void
_quit_cb (GtkWidget *button, gpointer data)
{
    (void)button; (void)data; /* Avoid compiler warnings */
    gtk_main_quit();
    return;
}

static void
shutdown (GtkWidget *button, gpointer data)
{
    (void)button; (void)data; /* Avoid compiler warnings */
    g_spawn_command_line_async(*command, &error);
    if (error != NULL) {
        g_warning("unable to launch: %s", error->message);
        }
    gtk_main_quit();
}

static gboolean
_label_update(gpointer data)
{
    GtkLabel *label = (GtkLabel*)data;
    char buf[256];
    memset(&buf, 0x0, 256);
    snprintf(buf, 255, "Turning off computer in  %d seconds.", --sec_expired);
    if (sec_expired == 0)
        {
        g_spawn_command_line_async(*command, &error);
        if (error != NULL) {
            g_warning("unable to launch: %s", error->message);
            }
        gtk_main_quit();
        }
    gtk_label_set_label(label, buf);
    return continue_timer;
}


int main(void)
{
    GtkWidget *window;
    GtkWidget *box;
    GtkWidget *boxl;
    GtkWidget *shutdown_button;
    GtkWidget *cancel_button;
    GtkWidget *label;
    GtkWidget *question;

    gtk_init(NULL, NULL);
    window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_widget_set_size_request(window, 250, 120);
    gtk_window_set_resizable (GTK_WINDOW(window), FALSE);
    gtk_window_set_keep_above (GTK_WINDOW (window), TRUE);
    gtk_window_stick (GTK_WINDOW (window));
    gtk_window_set_skip_taskbar_hint (GTK_WINDOW (window), TRUE);
    gtk_window_set_title (GTK_WINDOW (window), "Shutdown");
    g_signal_connect (G_OBJECT (window), "destroy", 
                    G_CALLBACK (gtk_main_quit),
                    NULL);
    box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 2);
    boxl = gtk_box_new (GTK_ORIENTATION_VERTICAL, 2);

    gtk_box_set_homogeneous (GTK_BOX (box), TRUE);
    gtk_container_add(GTK_CONTAINER(window),boxl);

    question = gtk_label_new("\nAre you sure you want to shutdown?");
    label = gtk_label_new("Turning off computer in  30 seconds.");

    shutdown_button = gtk_button_new_with_label("Shutdown");
    g_signal_connect(G_OBJECT(shutdown_button), "clicked", G_CALLBACK(shutdown), shutdown_button);

    cancel_button = gtk_button_new_with_label("Cancel");
    g_signal_connect(G_OBJECT(cancel_button), "clicked", G_CALLBACK(_quit_cb), NULL);

    gtk_box_pack_start (GTK_BOX(boxl), question, TRUE, TRUE, 0);
    gtk_box_pack_start (GTK_BOX(boxl), label, TRUE, TRUE, 0);

    gtk_box_pack_start (GTK_BOX (box), cancel_button, TRUE, TRUE, 10);
    gtk_box_pack_start (GTK_BOX(box), shutdown_button, TRUE, TRUE, 10);
    gtk_box_pack_start (GTK_BOX(boxl), box, TRUE, TRUE, 10);

    gtk_widget_show_all(window);

    g_timeout_add_seconds(1, _label_update, label);
    continue_timer = TRUE;
    start_timer = TRUE;

    gtk_main();
    return 0;
}

Deps: on debian, install libgtk-3-dev
and compile with:

Code: Select all

gcc  -o timer -fPIC timer.c `pkg-config --cflags --libs gtk+-3.0`

Then run the binary ./timer

This will do the same using yad, with the button labels you prefer. Just modify the SHUTDOWNCOMMAND to actually run your shutdown command instead of running geany

Code: Select all

#!/bin/bash

SHUTDOWNCOMMAND=geany

(  echo "99" ; sleep 1
   echo "90" ; sleep 1
   echo "80" ; sleep 1
   echo "70" ; sleep 1
   echo "60" ; sleep 1
   echo "50" ; sleep 1
   echo "40" ; sleep 1
   echo "30" ; sleep 1
   echo "20" ; sleep 1
   echo "10" ; sleep 1 ) |
  yad --progress --title="$TITLE $VERSION" --text=" Are you sure you want to shutdown? \n\n Turning off computer in 10 seconds \n\n Press Cancel to abort shutdown " \
  --percentage=0 --auto-close --auto-kill --button=CANCEL:1 --button=SHUTDOWN:0
[[ $? -eq 0 ]] && $SHUTDOWNCOMMAND

Thanks but after 3.0 the progress bar no longer works.
So many changes as the newer versions are not backward compatible. No gtk-icons support, right-click notification menu no longer works, entry is deprecated...
It's in quiet unstable now. Probably even more stuff will be removed when the old obsolete code derived from zenity is removed.

Bit off topic

Way off topic , but that's OK. Gives me a good excuse for throwing in another solution .... with Xdialog (we don't have a dedicated thread, do we?)

Xdialog's infobox can be configured to work similar to yad's text-info. Though it accepts only one button and the syntax is a bit weird it is simple and can be quite useful:

Code: Select all

for i in {5..0}; do
	echo  XXX
	echo "Turning off computer in $i seconds"
	echo XXX
	sleep 1
done | Xdialog --cancel-label "Abort shutdown"  -infobox "" 300x100 0
(($?)) && exit
Xdialog  -infobox "Continue now with shutdown commands" 300x100 4000

[stemsee]

How close can yad get to immitating a terminal? or swallowing one?

Aww, I lost the bet. I was betting on Fred the Netherlandian to be the first one to go off topic.
That's very minimal solution.

Why reinventing the hot water?
Bobby Copper aka YadBashBobby had that idea.
